As the number of people who enjoy coffee increases, tastes for the taste and aroma of coffee are becoming more sophisticated, and there are drip coffees made by grinding coffee beans and slowly adding hot water by hand, and espresso extracted using a coffee machine and manufactured using them. Interest in various coffee drinks is also increasing.

In addition, as consumer tastes vary, there is a significant difference in coffee sales depending on whether the tastes and tastes of professional coffee lovers are met. This is a result of the growing trend of coffee lovers looking for specific coffee shops according to the taste of coffee. places greater importance on the taste of coffee.

The main factors that determine the taste of coffee are time and speed, grinding density, water amount control, water temperature, water extraction pressure, and steam pressure, which must be uniformly implemented. The taste is determined by the barista's skill level and has a direct impact on the store's sales.

When hiring employees at a cafe, they must receive training in beverage making, and if an employee who has received training in beverage making quits while working, a new employee must be hired and trained from the beginning, making it difficult to manage the workforce. .

Hereinafter, an embodiment of the present invention described above will be described in detail with reference to the drawings.

Figure 1 shows a perspective view of an automatic liquid supply device according to an embodiment of the present invention. As shown in Figure 1, the automatic liquid supply device 10 of the present invention is formed on a case 100 on which a liquid container 20 containing syrup or sauce for beverage production is mounted and on the upper part of the case 100. It is installed in front of the pressurizing part 200 and case 100 that pressurizes the pump 21 of the liquid container 20, is installed so that the cup 30 can be mounted, and syrup or sauce supplied from the pump 21 After being provided to the cup 30, it includes a mix unit 300 that rotates the cup 30.

A guide hole 120 may be formed on the front of the case 100 to allow the pump 21 of the liquid container 20 to protrude. At this time, it is preferable that the vertical length of the guide hole 120 is the length at which the pump 21 is maximally compressed.

A plurality of automatic liquid supply devices 10 of the present invention can be installed in an unmanned beverage production device or a general cafe to provide syrup or sauce required for beverage production. That is, there are several automatic liquid dispensers equipped with a liquid container containing chocolate sauce, an automatic liquid dispenser equipped with a liquid container containing caramel sauce, and an automatic liquid dispenser equipped with a liquid container containing vanilla syrup. It can be placed to provide syrup or sauce necessary for beverage production.

In a conventional unmanned beverage manufacturing device, a liquid container is installed at the bottom of the work table, and when the motor operates, the liquid moves through a movable hose to supply syrup and sauce necessary for beverage manufacturing. At this time, there is a problem that hygiene management is difficult because the hose through which the syrup and sauce passes is not easy to clean. As the syrup and sauce hardens in the hose, it becomes difficult to supply the syrup and sauce, and a lot of pressure is applied to the supply of the syrup and sauce. As the need for it increases, there is a problem that the motor that supplies syrup and sauce is overloaded, causing the motor to malfunction. In addition, even in regular cafes, there is a problem that the taste of the drink varies depending on the barista because the pressure that pressurizes the pump is different depending on the barista.

Therefore, in order to solve this problem, an automatic liquid supply device 10 of the present invention is proposed to supply an accurate amount of syrup or sauce to a beverage. It will be described in more detail with reference to FIGS. 2 and 3.

Figures 2 and 3 show a perspective perspective view of an automatic liquid supply device according to an embodiment of the present invention. First, let us explain the case 100. As shown in FIGS. 2 and 3, one or more surfaces of the case 100 except the front are open so that the liquid container 20 can be mounted, and the automatic liquid supply device 10 according to an embodiment of the present invention ) is formed with the back open. A jig 110 is formed on the upper surface of the bottom of the case 100 to guide the position of the liquid container 20 and to secure the liquid container 20. In addition, a water level sensor 130 is provided at the rear to check the amount of syrup or sauce remaining in the liquid container 20, and the water level sensor 130 is preferably an ultrasonic sensor. If the syrup or sauce in the liquid container 20 is determined to be below a predetermined height from the water level sensor 130, a notification may be sent to the manager so that the liquid container 20 can be replaced.

At this time, in addition to the water level sensor 130, a weight sensor may be provided to measure the weight of the liquid container 20, or a configuration may be provided to calculate the amount of remaining syrup or sauce by measuring the number of times the pump 21 is pressurized. there is.

Next, the pressurizing unit 200 will be described. The pressurizing unit 200 is provided to pressurize the pump 21 so that the syrup or sauce in the liquid container 20 is supplied from the pump 21, and is a slide bar that pressurizes the pump 21 through an up and down reciprocating movement. (210), a connecting rod 230, one side of which is coupled to the slide bar 210 to transmit power so that the slide bar 210 moves up and down, and a connecting rod 230 coupled to the other side of the connecting rod 230. Whether the crank 220, which transmits power to reciprocate up and down, the pressurizing motor 240, which is coupled with the crank 220 and provides power to rotate the crank 220, and the liquid container 20 are accurately located at the designated positions. It includes a position sensor 250 that determines.

When the pressurizing motor 240 operates and rotates, the crank 220 rotates, and the connecting rod 230 coupled to the crank 220 reciprocates up and down due to the rotation of the crank 220, and the connecting rod 230 According to the up and down reciprocating motion, the slide bar 210 also moves up and down and pressurizes the pump 21. At this time, a groove convex upward may be formed in the lower part of the slide bar 210 to easily pressurize the upper part of the pump 21.

Lastly, the mix unit 300 will be described. The mix part 300 is formed on the front of the case 100, and includes a mounting part 310 on which the cup 30 is mounted, a rotation axis 320 coupled to the lower part of the mounting part 310, and a rotation axis 320 rotating clockwise or It includes a rotation motor 330 that provides power to rotate counterclockwise.

The operation of the pressurizing unit 200 of the automatic liquid supply device 10 will be described in more detail with reference to FIGS. 4 to 6.

Figure 4 shows a front cross-sectional view of an automatic liquid supply device according to an embodiment of the present invention. As shown in FIG. 4, the pressing portion 200 is formed in a crankshaft structure so that the slide bar 210 can reciprocate up and down. In the pressing unit 200 according to an embodiment of the present invention, when the pressing motor 240 operates and rotates, the crank 220 rotates, and the connecting rod 230 performs an up and down reciprocating movement due to the rotation of the crank 220. While doing so, the slide bar 210 also moves up and down. At this time, the slide bar 210, which reciprocates up and down due to the up and down reciprocating motion of the connecting rod 230, pressurizes the pump 21 of the liquid container 20.

Figure 4 (a) shows the normal state, and Figure 4 (b) shows that when the pressing motor 240 operates and rotates, the crank 220 rotates due to the rotation of the pressing motor 240, and the crank 220 rotates. By rotation, the connecting rod 230 and the slide bar 210 move downward and pressurize the pump 21 of the liquid container 20.

That is, the pump 21 performs an up and down reciprocating movement once, thereby pressurizing the pump 21 of the liquid container 20 once, and the pressurizing unit 200 pressurizes the pump 21 of the liquid container 20 once. Since the amount of syrup or sauce is supplied at a constant rate, the drink can be manufactured with a consistent taste.

If the amount of syrup or sauce supplied when the pressurizing unit 200 pressurizes the pump 21 of the liquid container 20 once is 10ml, if pressurized twice, 20ml will be supplied, and if pressurized three times, 30ml will be supplied. , the supply amount of syrup or sauce can be adjusted through the number of pressurizations of the pump 21.

As the syrup or sauce contained in the liquid container (20) is used, the syrup or sauce contained in the liquid container (20) becomes less than the set amount, so it is necessary to replace the liquid container (20) or replenish the syrup or sauce in the liquid container (20). The amount of syrup or sauce remaining in the liquid container (20) must be checked.

At this time, the amount of syrup or sauce remaining in the liquid container 20 is determined by the water level sensor 130 detecting the water level of the syrup or sauce. If it is determined that the syrup or sauce in the liquid container 20 is below the standard height, a notification can be sent to the manager to replace the liquid container 20 or replenish the syrup or sauce in the liquid container 20.

Alternatively, a weight measurement sensor is provided at the bottom of the case 100 on which the liquid container 20 is mounted, and if the weight of the liquid container 20 is below a certain value, it is determined that the syrup or sauce in the liquid container 20 is below the standard. Thus, a notification can be sent to the manager to replace the liquid container 20 or replenish syrup or sauce in the liquid container 20.

Alternatively, a method of calculating the amount of syrup or sauce remaining in the liquid container 20 by measuring the number of times the pump 21 is pressurized may be used. The liquid container 20 contains 500 ml of syrup or sauce, and when the pressurizing part 200 pressurizes the pump 21 of the liquid container 20 once, 10 ml of the supplied syrup or sauce is discharged. Assuming that a notification is sent to the manager when the syrup or sauce in the liquid container (20) becomes 50 ml or less, if the pump (21) of the liquid container (20) is pressed 45 times, the syrup or sauce in the liquid container (20) It is calculated that 50ml remains, and a notification is sent to the manager so that the liquid container 20 can be replaced or syrup or sauce can be replenished in the liquid container 20.

Since the amount of syrup or sauce supplied from the liquid container 20 is determined by the length of the pump 21 of the contracted liquid container 20, the amount of syrup or sauce supplied from the pump 21 is determined by the length of the pump 21. You can change the amount of syrup or sauce supplied by modifying .

Figure 5 shows a front cross-sectional view of an automatic liquid supply device according to a modified example of an embodiment of the present invention. As shown in FIG. 5 , an embodiment of controlling the amount of syrup or sauce discharged by the pressurizing unit 200 is shown by forming different lengths of the pumps 21 coupled to the liquid container 20.

Assuming that the length of the pump 21 in Figure 5 (a) is d1, the length of the pump 21 in Figure 5 (b) is d2, and the length of the pump 21 in Figure 5 (c) is d3, the liquid container 20 The length of the pump 21 coupled to is in the order d1 < d2 < d3, and the amount of syrup or sauce supplied when pressurized once is also in the order d1 < d2 < d3. At this time, as the length of the pump 21 changes, the vertical length of the guide hole 120 of the case 100 may also be changed to match the length of the pump 21.

That is, in Figure 5 (a), 10 ml of syrup or sauce is supplied when the pump 21 of the liquid container 20 is pressed, and in Figure 5 (b), when the pump 21 of the liquid container 20 is pressed. 20ml of syrup or sauce is supplied, and Figure 5(c) assumes that when the pump 21 of the liquid container 20 is pressurized, 30ml of syrup or sauce is supplied.

To make a caramel macchiato, an espresso shot is extracted from an espresso machine, and caramel sauce is added to the espresso shot. When 30 ml of caramel sauce needs to be added to produce caramel macchiato, Figure 5 (a) shows that the pump 21 of the liquid container 20 must be pressed three times by the pressurizing unit 200, but Figure 5 (c) ) can reduce the beverage production time because the pressurizing unit 200 only needs to pressurize the pump 21 of the liquid container 20 once.

However, as shown in (b) of FIG. 5, when the pump 21 of the liquid container 20 is pressurized once and the caramel syrup supplied is 20 ml, the caramel syrup cannot be accurately supplied to 30 ml.

Therefore, in order to increase beverage manufacturing accuracy, there is an inconvenience in that the amount of syrup or sauce discharged at one time by the pressurizing unit 200 must be set to a small amount and the pressurizing unit 200 must be pressed several times.

A plan to resolve this inconvenience is shown in FIG. 6. Figure 6 shows the amount of syrup or sauce supplied from the liquid container 20 by changing the contracted length of the pump 21 of the liquid container 20 by controlling the pressurizing unit 200.

Figure 6 shows a front cross-sectional view of an automatic liquid supply device according to another modification of an embodiment of the present invention. Figure 6 shows that the contraction length of the pump 21 coupled to the liquid container 20 is adjusted by the pressurizing unit 200 to control the amount of syrup or sauce supplied from the pump 21 by the pressurizing unit 200. Another embodiment is shown.

Figure 6 (a) is an example in which the pump 21 of the liquid container 20 is pressurized to only 1/2, and Figure 6 (b) is an example in which the pump 21 of the liquid container 20 is pressurized to only 2/3. This is one example, and Figure 6(c) shows an example in which the pump 21 of the liquid container 20 is pressurized to the end.

This is because the rotation angle of the crank 220 is controlled by the pressurizing motor 240 of the pressurizing unit 200 to change the length at which the pump 21 of the liquid container 20 is contracted, thereby controlling the syrup supplied from the pump 21. Or adjust the amount of sauce.

At this time, the operation of the pressing unit 200 may change depending on the type of the pressing motor 240. If the pressurizing motor 240 coupled with the crank 220 is a cam motor, the rotation angle of the crank 220 can be controlled, but the controlled rotation angle is fixed and a certain amount of syrup or sauce is always supplied until controlled again. will be supplied.

That is, when the pressurizing unit 200 is controlled to pressurize the pump 21 of the liquid container 20 so that 5 ml of syrup or sauce is supplied from the liquid container 20, the syrup or sauce supplied from the liquid container 20 is again 5ml of syrup or sauce will be supplied until there is an external control to change the amount of sauce.

However, when the pressurizing motor 240 coupled with the crank 220 is a stepping motor, the rotation of the motor is controlled to increase the amount of syrup or sauce supplied from the liquid container 20 to 8ml when pressurizing once, and when pressurizing the second time, the amount of syrup or sauce supplied from the liquid container 20 is 8ml. Since the rotation of the stepping motor can be easily controlled so that the amount of syrup or sauce supplied from the liquid container 20 can be controlled to 6ml, the syrup or sauce supplied from the liquid container 20 according to the customer's requirements. The amount can be easily changed.

I would like to explain it in more detail using an example. It is assumed that 25 ml of syrup or sauce must be supplied to produce a beverage, and that the amount of syrup or sauce supplied when the pump 21 of the liquid container 20 is pressed all the way is 15 ml.

When the pressurizing motor 240 is a cam motor, the pump 21 of the liquid container 20 is controlled to pressurize only 5ml, so that the slide bar 210 presses the pump 21 of the liquid container 20 five times to pressurize the pump 21 of the liquid container 20 to 25ml. Ensure that syrup or sauce is supplied.

However, when the pressurizing motor 240 is a stepping motor, it is controlled to pressurize enough to supply 15ml once and 10ml twice, so that the slide bar 210 pressurizes the pump 21 of the liquid container 20 twice. do. Alternatively, the pump 21 of the liquid container 20 is pressurized twice by controlling the pump 21 of the liquid container 20 to be pressurized enough to supply 10 ml once and 15 ml twice, or controlled to be pressurized enough to supply 13 ml once and 12 ml twice. Thus, the pump 21 of the liquid container 20 may be pressurized twice.

Therefore, when the stepping motor is connected to the crank 220, the amount of syrup or sauce can be accurately supplied and the beverage production time can be shortened.

When customers order a drink, they can adjust the sweetness of the drink. When using an unmanned beverage manufacturing device, you can order a drink by changing the sweetness of the drink through the kiosk, and the unmanned beverage manufacturing device can produce a beverage by changing the amount of syrup or sauce according to the order information for the beverage with the changed sugar content. . Even in regular cafes, when ordering at a kiosk or face-to-face with a staff member, you can change the sweetness of the drink. Therefore, a customized beverage that reflects the customer's taste can be manufactured and provided to the customer.

In the case of an unmanned beverage production device, the operation of the pressurizing unit 200 that pressurizes the pump 21 may be automatically controlled by a control signal from the control unit according to the beverage order information, and in the case of a general cafe, an automatic liquid supply device ( 10) An input unit is provided to input the amount to be supplied, or a bar code or QR code that can check beverage order information is attached to the cup, and the liquid automatic supply device reads the bar code or QR code to operate the pressurizing unit 200. This can be controlled.

Figure 7 shows a perspective view of the mix unit of the automatic liquid supply device according to an embodiment of the present invention. As shown in FIG. 7, a cylindrical mounting part 310 is provided so that the cup 30 can be inserted therein. When the cup 30 is mounted on the mounting part 310, the rotation motor 330 operates, The contents of the cup 30 may be mixed by rotating the mounting part 310 clockwise or counterclockwise more than n times based on the vertical axis by the rotation axis 320.

In the conventional unmanned beverage manufacturing device, the beverage manufacturing robot 110 had to stir and mix using a stick or mixer to mix other ingredients when manufacturing a beverage, but there is a limit to performing the stirring operation with the beverage manufacturing robot 110. The problem is that it does not mix well and takes a long time to prepare the drink. In addition, even in a regular cafe, the barista must mix the contents of the cup 30 by stirring it with a stick or mixing device.

However, the automatic liquid supply device 10 of the present invention can easily mix a plurality of ingredients in the cup 30 by the mixing unit 300.

Figure 8 shows a front cross-sectional view of the mix unit of the automatic liquid supply device according to an embodiment of the present invention. As shown in Figure 8, in order to manufacture a caramel macchiato, an espresso shot is extracted from an espresso machine, and the espresso shot is placed in a cup 30.

Next, the cup 30 containing the espresso shot is mounted on the mounting part 310 of the mix unit 300, and the caramel sauce is supplied to the cup 30 containing the espresso shot from the pump 21, so that the caramel sauce is in the cup. It is added to the espresso shot contained in (30). When manufacturing caramel macchiato, when 30ml of caramel sauce needs to be added, the pump 21 is pressurized by the operation of the pressurizing part 200, and 30ml of caramel sauce is supplied into the cup 30.

Initially, as shown in (a) of Figure 8, the espresso shots and caramel sauce are layered and separated. However, when the cup 30 mounted on the mounting unit 310 is rotated clockwise or counterclockwise about the vertical axis by rotation of the rotation axis 320 at least once, espresso is produced as shown in (b) of FIG. 8. The shot and caramel sauce are mixed.

After the espresso shot and caramel sauce are mixed, steamed milk is supplied to the cup (30) to complete a warm caramel macchiato, or after the espresso shot and caramel sauce are mixed, cold milk and ice are supplied to the cup (30) to complete an iced caramel macchiato. Can be provided to customers.

At this time, the mix unit 300 of the present invention is not formed in the automatic liquid supply device 10, but is formed so that the mix unit 300 can move linearly, so that the liquid container 20 containing the syrup or sauce required for beverage production is provided. The mix unit 300 can be moved in a movable direction toward the location.

That is, assuming that liquid containers 20 such as chocolate sauce, caramel sauce, vanilla syrup, and hazelnut syrup are mounted on the case 100 and arranged in a row, when manufacturing hot chocolate, the mix unit 300 is used to prepare the chocolate sauce. It can be formed to move towards and, when making vanilla latte, move towards vanilla syrup.

Alternatively, the mix unit 300 is formed in a separate location, and after the syrup or sauce is supplied to the cup 30, the cup 30 is mounted on the mounting part 310 of the mix unit 300 to collect the ingredients in the cup 30. can also be mixed.

Figure 9 shows an enlarged perspective view of the mounting part showing the O-ring groove and through hole formed in the mounting part of the automatic liquid supply device according to an embodiment of the present invention, and Figure 10 shows the automatic liquid supply device according to an embodiment of the present invention. A perspective view of the O-ring showing the O-ring coupled to the O-ring groove of the mounting portion of the supply device is shown.

As shown in FIG. 9, an O-ring groove 311 having a concave groove shape concave inward is formed at one point of the upper outer surface of the mounting portion 310. A plurality of through holes 313 are formed in the O-ring groove 311 at regular intervals. An O-ring 315 is coupled to this O-ring groove 311, and the O-ring 315 is coupled such that a portion of the O-ring 315 protrudes into the inside of the mounting portion 310 by a plurality of through holes 313 formed in the O-ring groove 311.

Forming the O-ring groove 311 and coupling the O-ring 315 to the O-ring groove 311 in this way means that when the cup 30 is mounted on the mounting portion 310, the mounting portion 310 is formed through the plurality of through holes 313. Because the O-ring 315 protruding in the inner direction is in close contact with the outer surface of the cup 30, when the mounting part 310 is rotated to mix the plurality of ingredients contained in the cup 30, the cup 30 is attached to the mounting part 310. It not only prevents the cup 30 from spinning around and being separated from the mounting part 310, but also ensures that the cup 30 is stable on the mounting part 310 when the cup 30 is mounted on the mounting part 310. It can be installed with .

This means that if the O-ring groove 311 and the O-ring 315 are not provided in the mounting part 310, when the cup 30 is mounted on the mounting part 310 and the mounting part 310 is rotated, the cup 30 is not attached to the mounting part 310. This is to solve the problem of the beverage and sauce contained in the cup 30 not being mixed well due to rotation around the cup 310. The O-ring 315 protruding toward the inside of the mounting portion 310 through the through hole 313 is attached to the cup. While (30) is stably mounted on the mounting part 310, the cup 30 is in close contact with the mounting part 310 so that the cup 30 can rotate together with the mounting part 310 when the mounting part 310 rotates. This is to prevent the cup from spinning around or being detached from the mounting portion 310 so that the beverage and sauce contained in the cup 30 can be mixed well.

Here, the O-ring 315 is preferably made of elastic silicon or rubber in a circular ring shape as shown in Figure 10, and allows the cup 30 to be stably mounted on the mounting portion 310. It is sufficient to have an adhesive force so that a gap does not occur between the cup 30 and the mounting part 310 and the cup 30 rotates together with the mounting part 310 when the mounting part 310 rotates.

Figure 11 shows an enlarged perspective view of the inside of a cup mounted on the mix unit of the automatic liquid supply device according to an embodiment of the present invention. As shown in FIG. 9, a cross-shaped protrusion 31 is formed on the lower surface of the cup 30 and protrudes at a predetermined height. This is formed to ensure that the ingredients in the cup are well mixed when the cup 30 rotates.

The technical idea of the present invention should not be interpreted as limited to the above-described embodiments. Not only is the scope of application diverse, but various modifications can be made at the level of those skilled in the art without departing from the gist of the present invention as claimed in the claims. Therefore, such improvements and changes fall within the scope of protection of the present invention as long as they are obvious to those skilled in the art.
